An unauthorized SSL certificate has been found in the wild issuedthe DigiNotar Certificate Authority, obtained through a securitycompromise with said company. Debian, like other softwaredistributors, has as a precaution decided to disable the DigiNotarRoot CA by default in its ca-certificates bundle.

For other software in Debian that ships a CA bundle, like theMozilla suite, updates are forthcoming.

For the oldstable distribution (lenny), the ca-certificates packagedoes not contain this root CA.

For the stable distribution (squeeze), the root CA has beendisabled starting ca-certificates version 20090814+nmu3.

For the testing distribution (wheezy) and unstable distribution(sid), the root CA has been disabled starting ca-certificatesversion 20110502+nmu1.

We recommend that you upgrade your ca-certificates packages.
